Dr. Mehmet Oz and his son, Oliver, had a heart-palpitation-inducing steak dinner at Morton’s in Hackensack, NJ, this week. A few nights before Father’s Day, the popular TV doc and his son were “salivating” over their Cajun rib-eye and New York strip steaks, said a source — a rare opportunity for them since Oz’s wife, Lisa, is a vegetarian. Dr. Oz is a practicing heart surgeon. His publicist responded: “I can confirm the results of your steak-out. I’m told that said steak was a lean cut.”
